When i try distributed simulation i all time get this error in remote machine

?? Read error on fin: Error Occurred of 44
?? Read error on fin: Error Occurred of 11

everything works fine even with this error but after some tome sim crush.

If i try to sim on local with two shells launched all works fine.
As i found this happens only on remote pc if your tracker launched on your local ps, if you launch tracker on remote pc you get this eror on local and again simulation crush after some time.
Operating system :windows 7
All firewalls turned off.

Thanks for Help.
